Infinity PR6510CS Primus Series Automotive Component System

New Primus speakers feature our patented Plus One polypropylene woofers which feature more radiating cone area for increased output and edge-driven tweeters for better high frequency dispersion. Speakers are super clear at the top with vocals, horns and strings and deliver big bass with plenty of slam. Long story short: superior sound top to bottom. True 4 ohm architecture gives the amplifier room to reach peak power for increased depth and detail. In addition to passing demanding reliability and environmental testing, all speakers are individually voiced by some of the world's best transducer engineers to authenticate the Infinity sound. It's not a coincidence that Infinity is one of the world's top-selling car audio speaker brands.

(25mm) Impedance 2.7 ohms Polypropylene cones with up to 35% more radiating cone area than other cones in the same class provide higher sensitivity, increased low frequency output and better tonal balance. Hi-roll rubber surrounds using automotive grade materials result in cleaner reproduction and higher durability whether it's easy listening or time to show and shine. Infinity speakers have to undergo a testing process that would destroy lesser speakers. Infinity freezes them, bakes them, shakes them, blasts them with ultraviolet light and drives them at full power for days at a time.
